Description

Technical Field

[0001] This invention relates to the field of carbon emission detection technology, and more specifically, to a method for detecting carbon emission concentration during waste incineration. Background Technology

[0002] Since 2010, my country's municipal solid waste production has increased annually at an average growth rate of 5%, making waste incineration a key technology for harmless treatment and disposal. Currently, my country's waste incineration capacity has surpassed that of the United States, Japan, and the European Union, ranking first in the world, and it continues to grow. With the introduction of my country's "dual-carbon" development strategy and the establishment of a carbon trading market, the carbon emissions of the waste-to-energy industry are receiving increasing attention. Currently, the methods for detecting carbon emission concentrations in the domestic waste-to-energy industry include the emission factor method, the mass balance method, and the continuous online monitoring method. The first two methods calculate carbon emissions; the emission factor method calculates carbon emissions using emission factor data, while the mass balance method calculates carbon balance by subtracting non-carbon dioxide carbon output from the input carbon content during the production process. The continuous online monitoring method, also known as the direct measurement method, uses a continuous emission monitoring system (CEMS) to measure the CO2 concentration and flue gas flow rate in the emitted gases in real time, thus obtaining continuous and real-time carbon emission monitoring results.

[0003] However, existing detection methods have the following drawbacks: 1) Although the emission factor method is simple to use, its accuracy is greatly affected by factors such as the nature of the waste and operating conditions; 2) The mass balance method requires data on the carbon content in fuel, flue gas, and residues, which involves many parameters, a complicated detection procedure, and its accuracy is greatly affected by actual on-site conditions; 3) Although the continuous online monitoring method has the advantages of timeliness and less raw data analysis, the cost of equipment operation and maintenance is high due to the need for continuous detection.

[0004] Therefore, there is an urgent need for a method to detect carbon emission concentrations in the waste incineration process that is highly accurate and has low detection costs. Summary of the Invention

[0005] The purpose of this invention is to provide a method for detecting carbon emission concentration during waste incineration, thereby solving at least one problem existing in the prior art.

[0006] To achieve the above objectives, the present invention provides a method for detecting carbon emission concentration during waste incineration, the method comprising:

[0008] The carbon dioxide emission concentration of a preset type of waste combustion is obtained based on the amount of flue gas produced per unit mass of waste combustion, the volume of CO2 produced per unit mass of waste combustion, the concentration of O2 in the air at the waste combustion site, and the concentration of O2 in the flue gas at the waste combustion site.

[0009] Furthermore, a preferred method includes, when the concentration of O2 in the flue gas at the waste incineration site is the average concentration of O2 in the flue gas at the waste incineration site, the carbon dioxide emission concentration is the average concentration of carbon dioxide in the flue gas produced by a preset type of waste incineration.

[0010] The average carbon dioxide concentration in the flue gas produced by burning a unit mass of waste is obtained based on the amount of flue gas produced, the volume of CO2 produced, the concentration of O2 in the air at the waste combustion site, and the concentration of O2 in the flue gas at the waste combustion site. This is achieved using the following formula:

[0011]

[0023] Furthermore, a preferred method includes obtaining the concentration of O2 in the flue gas at the waste incineration site by monitoring it using an oxygen sensor at the waste incineration site.

[0024] The present invention also includes a carbon emission concentration detection system for the waste incineration process, which performs the above-described carbon emission concentration detection method for the waste incineration process; the system includes a data acquisition unit and a carbon dioxide emission concentration acquisition unit;

[0030] 3) Applicable to various types of waste incineration power generation equipment.

[0031] To achieve the foregoing and related objectives, one or more aspects of the invention include the features that will be described in detail below and particularly pointed out in the claims. The following description details certain exemplary aspects of the invention. However, these aspects indicate only a few of the various ways in which the principles of the invention can be used. Furthermore, the invention is intended to include all such aspects and their equivalents. Attached Figure Description

[0032] Figure 1 This is a schematic diagram illustrating the process principle of a method for detecting carbon emission concentration during waste incineration according to an embodiment of the present invention. Detailed Implementation

[0033] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Where specific techniques or conditions are not specified in the embodiments, they should be performed in accordance with the techniques or conditions described in the literature in this field, or according to the product instructions. Reagents or instruments whose manufacturers are not specified can be purchased from legitimate channels as conventional products.

[0034] The various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] Figure 1The process principle of the carbon emission concentration detection method during waste incineration according to an embodiment of the present invention is described in detail. Specifically, Figure 1 This is a schematic diagram illustrating the flow principle of the carbon emission concentration detection method during waste incineration according to an embodiment of the present invention. Figure 1 As shown, the method includes steps S110 to S120.

[0036] S110. Based on the preset waste type, obtain the amount of flue gas generated per unit mass of waste combustion, the volume of CO2 generated per unit mass of waste combustion, and the concentration of O2 in the air at the waste combustion site, and measure the concentration of O2 in the flue gas at the waste combustion site.

[0037] Specifically, the theoretical flue gas volume is defined as the volume of combustion gas produced when waste is completely burned with the theoretical amount of air. In practice, if the type of waste is known, its composition is also known. Let C, H, N, O, S, Cl, and W represent the mass ratios of carbon, hydrogen, nitrogen, oxygen, sulfur, chlorine, and water per unit of waste, then the theoretical flue gas volume can be obtained. In other words, the theoretical flue gas composition and the CO2 content can be calculated based on the waste composition, or an estimated value can be used depending on the actual situation. Typical flue gas compositions include carbon dioxide, sulfur dioxide, hydrogen chloride, oxygen, nitrogen, and water.

[0038] Taking a certain type of municipal solid waste as an example, the mass ratios of carbon, hydrogen, nitrogen, oxygen, sulfur, chlorine, and water in a unit of waste are: 19.40%, 2.20%, 14.00%, 0.23%, 0.40%, and 45.30%, respectively. The theoretical flue gas volume under equivalent air conditions can be obtained, but is not limited to, through the following formula:

[0039] V(m 3 / kg)=0.1876C+0.112H++0.07S+0.008N+0.0124W

[0040] In practice, the concentration of O2 in the flue gas at the waste incineration site is monitored by an oxygen sensor at the incineration site. Moreover, for existing waste-to-energy incineration equipment, an oxygen sensor is a necessary component, and no additional sensors are required.

[0041] S120. Based on the amount of flue gas produced by burning a unit mass of waste, the volume of CO2 produced by burning a unit mass of waste, the concentration of O2 in the air at the waste combustion site, and the concentration of O2 in the flue gas at the waste combustion site, obtain the carbon dioxide emission concentration of the preset type of waste combustion.

[0042] When the concentration of O2 in the flue gas at the waste incineration site is the same as the average concentration of O2 in the flue gas at the waste incineration site, the carbon dioxide emission concentration is the average concentration of carbon dioxide in the flue gas produced by the preset type of waste incineration.

[0043] The average carbon dioxide concentration in the flue gas produced by burning a unit mass of waste is obtained based on the amount of flue gas produced, the volume of CO2 produced, the concentration of O2 in the air at the waste combustion site, and the concentration of O2 in the flue gas at the waste combustion site. This is achieved using the following formula:

[0044]

[0045] Wherein, CO2 represents the average concentration of carbon dioxide, in percentage (%); O 2,Measure This indicates the average concentration of O2 in the flue gas, expressed in %; O 2,Air The concentration of O2 in the air is expressed as a percentage (%); F represents the theoretical flue gas volume per unit mass of waste incinerated, expressed as m³. 3 / t;F C This represents the volume of CO2 produced by burning a unit mass of waste, in cubic meters (m³). 3 / t. It should be noted that the above theoretical flue gas volume and CO2 volume are values ​​under the condition of complete combustion of equivalent air. In addition, the flue gas volume and other statistics are all calculated on a daily basis. In actual implementation, hourly statistics can also be used, and other variables can be adjusted accordingly.

[0046] It should be noted that F and F C It can be calculated from the composition of the waste (which can be obtained by those skilled in the art based on existing technology), or it can be estimated; O 2,Air A volume fraction of 21% oxygen in the air is generally used, but in some special areas (such as high-altitude areas), adjustments need to be made according to local conditions; O 2,Measure It is the monitored value of O2 in flue gas. In waste incineration power plants, the concentration of O2 in flue gas is usually monitored.

[0047] In other words, only the theoretical amount of flue gas produced per unit mass of waste and the amount of CO2 in it (under the condition of complete combustion of equivalent air) are needed. Combined with the monitoring data of O2 concentration in the flue gas on site, the CO2 concentration in the flue gas can be calculated. The detection data of O2 concentration is data that waste incineration power plants usually have, so the existing detection data of waste incineration power plants can be used, and therefore no new monitoring equipment is needed.

[0048] This invention also protects a carbon emission concentration detection system for waste incineration processes, which executes the aforementioned carbon emission concentration detection method for waste incineration processes. The system includes a data acquisition unit and a carbon dioxide emission concentration acquisition unit. The data acquisition unit is used to acquire, based on a preset waste type, the amount of flue gas generated per unit mass of waste combustion, the volume of CO2 generated per unit mass of waste combustion, and the concentration of O2 in the air at the waste combustion site, and to measure the concentration of O2 in the flue gas at the waste combustion site. The carbon dioxide emission concentration acquisition unit is used to acquire the carbon dioxide emission concentration of a preset type of waste combustion based on the amount of flue gas generated per unit mass of waste combustion, the volume of CO2 generated per unit mass of waste combustion, the concentration of O2 in the air at the waste combustion site, and the concentration of O2 in the flue gas at the waste combustion site.

[0049] Specifically, the basic algorithm is built in. When the collected data is entered into the carbon emission concentration detection system for the waste incineration process, the system will automatically match the data based on the data type of the input data with the data on the amount of flue gas produced per unit mass of waste combustion, the volume of CO2 produced per unit mass of waste combustion, and the concentration of O2 in the air at the waste combustion site, and then calculate the carbon dioxide emissions.

Based on the amount of flue gas produced per unit mass of waste combustion, the volume of CO2 produced per unit mass of waste combustion, the concentration of O2 in the air at the waste combustion site, and the average concentration of O2 in the flue gas at the waste combustion site for each hour, the average concentration of carbon dioxide in the flue gas produced by the preset type of waste combustion for each hour is obtained through the following formula: in, The average concentration of carbon dioxide for each hour is expressed in % (%). The average concentration of O2 in flue gas over each hour, expressed as % This indicates the concentration of O2 in the air, expressed in % (%). F This represents the theoretical flue gas volume per unit mass of waste incinerated, in m³. 3 / t; F C This represents the volume of CO2 produced by burning a unit mass of waste, in cubic meters (m³). 3 / t.
